Another common problem, particularly in more rural areas. Power cuts can
cause problems and at best mean you can't work while the power is out. At worst
you can experience data corruption to your file server.

Protecting yourself against this eventuality is both simple and low cost.
A UPS (Uninterruptible Power Supply) will keep your fileserver safe and
allow an orderly shutdown before the power is cut. Typically the UPS will keep the server up for about 15 minutes and will
automatically shutdown your server if the power is not restored within this
time. You can of course choose to have a larger UPS for more time and even
keep your router and phone system alive to allow at least some measure of
working while the power is out.
